Interpolymer Stain Blocking Paints

INTERPOLYMER has designed aqueous SYNTRAN® acrylic, cationic polymer dispersions that can be used as functional binders in high quality stain-blocking primers and paints.


On wood and cork, tannates and other extractives are permanently blocked, thus preventing the unsightly discoloration of white or light-colored topcoats. On walls and ceilings, nicotine stains, water stains, fat, graffitis etc. can be effectively covered and blocked, thus allowing the renovation of heavily stained rooms in restaurants, pubs, living areas etc. Apart from stain-blocking, these cationic polymers also provide excellent adhesion to a wide variety of substrates.
